Hi All,

I want to delete a entry = 014 in Infoobject = data provider since it is no more needed. **

When I go to this Infoobject-> Maintain master data anddelete it, a message Pop’s up

When I Check using Tcode  SLG1, I see

When I check in SID table of the Infoobject, I see below.

How do I delete it? Please help.
